(CNET) – If ever a story called for the use of an emoticon, this would be the one: text messaging volume in the U.S. has declined for the first time ever, according to a new research report.

Regardless of whether the emoticon you’d assign to the story is a smiley or a sad face, it’s worth noting that after years as a growing communications medium, texting may be starting to fall victim to new market trends, at least insofar as it generates revenues for wireless carriers.

In a report looking at the U.S. mobile data market in the third quarter, Chetan Sharma wrote that although other western countries have already started to see falling revenue in the messaging segment, this was the first time that American carriers have both mirrored that revenue pattern and seen a drop in the total volume of SMS messages sent.
